【摘要】 以提高微博网站的可用性为目的,本文将可用性工程理论和方法引入到对微博网站的评价测试中。在对国内外研究现状进行了深入分析的基础上,本文对影响微博网站可用性质量的关键点——用户界面,进行了研究与测试。本文从可用性工程理论开始,介绍了以用户为中心的软件产品的开发过程,及开发过程中所用到的可用性设计准则、界面设计准则和评价方法,在此基础上,对各评价方法的优缺点进行了比较。根据微博网站的一般特征,本文分析出微博网站的可用性评价要素,为评价提供了具体的量化指标,即可用性评价指标体系,并选用启发式评估法与用户测试法,建立了改进的启发式评估准则,结合改进的启发式评估准则与可用性指标体系,形成了两级评价机制,保证了微博网站的可用性质量。本文以新浪和腾讯微博网站为例,采用了德尔菲法和层次分析法计算微博网站可用性评价体系的指标权重,之后用模糊综合评价法对两者的可用性质量进行综合评价,从整体上比较两者的高低；再采用改进的启发式评价方法,分析新浪微博网站用户界面的可用性问题,并提出修改建议。笔者希望通过本次研究,为微博网站的可用性建设提供一些可操作性的建议,为微博网站的可用性评价方法的发展起到一定的促进作用。更多还原

【Abstract】 In order to improve the usability of Microblog site, the theory and method of usability engineering is used to evaluation process of Microblog site in this paper. Based on the in-depth analysis of the present research situation at home and abroad, a research has been conducted on the key point——-user interface, which affects the Microblog site.In this paper, which starts with the usability engineer theory, the development of user-center, the guidelines of usability design, and the guideline-evaluation method of user interface design is introduced. Based on the analysis, which compares the advantages and disadvantages of those methods, Heuristic Evaluation and user testing are suitable for evaluation. Improved Heuristic Evaluations is built after the analysis. And the key evaluating element of Microblog site has been analyzed, which offers specific measurement indicators for Microblog site. In order to ensure the development quality of usability, a Two-Stage evaluation mechanism is built up in this paper.Sina and Tencent Microblog sites are mentioned as two examples, and integrate Delphi method and AHP to determine the index weight, then use fuzzy comprehensive evaluate method to evaluation the two examples. The Improved Heuristic Evaluations can be used on how to improve the usability quality of the user interface of Sina Microblog. In this research, some maneuverable suggestions to the Microblog site usability are provided, and will contribute to the development of the usability evaluation in the future.更多还原
